[PATCH v3 00/15] Forward MSI-X vector enable error code in pci_alloc_irq_vectors_affinity()

The primary objective of this patch series is to change the behaviour
of pci_alloc_irq_vectors_affinity() such that it forwards the MSI-X enable
error code when appropriate. In the process, though, it was pointed out
that there are multiple places in the kernel which check/ask for message
signalled interrupts (MSI or MSI-X), which spawned the first patch adding
PCI_IRQ_MSI_TYPES. Finally the rest of the chain converts all users to
take advantage of PCI_IRQ_MSI_TYPES or PCI_IRQ_ALL_TYPES, as
appropriate.

Piotr Stankiewicz (15):
PCI/MSI: Forward MSI-X vector enable error code in
pci_alloc_irq_vectors_affinity()
PCI: Add macro for message signalled interrupt types
PCI: Use PCI_IRQ_MSI_TYPES where appropriate
ahci: Use PCI_IRQ_MSI_TYPES where appropriate
crypto: inside-secure - Use PCI_IRQ_MSI_TYPES where appropriate
dmaengine: dw-edma: Use PCI_IRQ_MSI_TYPES where appropriate
drm/amdgpu: Use PCI_IRQ_MSI_TYPES where appropriate
IB/qib: Use PCI_IRQ_MSI_TYPES where appropriate
media: ddbridge: Use PCI_IRQ_MSI_TYPES where appropriate
vmw_vmci: Use PCI_IRQ_ALL_TYPES where appropriate
mmc: sdhci: Use PCI_IRQ_MSI_TYPES where appropriate
amd-xgbe: Use PCI_IRQ_MSI_TYPES where appropriate
aquantia: atlantic: Use PCI_IRQ_ALL_TYPES where appropriate
net: hns3: Use PCI_IRQ_MSI_TYPES where appropriate
scsi: Use PCI_IRQ_MSI_TYPES and PCI_IRQ_ALL_TYPES where appropriate
